The four major manifestations of developmental toxicity are death, structural abnormality, altered growth, and functional deficit. The relationship among these manifestations may vary with increasing dose and, especially at higher doses, death of the conceptus may preclude expression of other manifestations.

Why is Occupational Toxicology important?

The objective of the occupational toxicologist is to prevent adverse health effects in workers that result from their work environment. Because the work environment often presents exposures to complex mixtures, the occupational toxicologist must also recognize exposure combinations that are particularly hazardous.

DOI: 10.1097/AOG.0b013e318206c07c Abstract Background: Labetalol is commonly used for control of hypertension in pregnancy. A component of the workup for new-onset hypertension in pregnancy often includes a urine drug screen.

Does labetalol interact with drug immunoassays in pregnancy?

Background: Labetalol is commonly used for control of hypertension in pregnancy. A component of the workup for new-onset hypertension in pregnancy often includes a urine drug screen. A labetalol metabolite is structurally similar to amphetamine and methamphetamine, thus causing potential cross-reactivity in drug immunoassays.
